I'm looking for a pot like the one on the Korg Monotron that has an LED

The Rate pot flashes depending on the value, any idea where I could find this. I've bought the smaller pots that are black tipped, but I'm not sure if what I'm looking for is a pot or if they just inserted an LED and used a clear cap.

 

Something like this with a back-light knob?
